Several times now I've posted examples of Loetz decors that are confusing to me and other Loetz collectors. I'm speaking of "Norma", "Delphi", and "Silberiris" decors. My purpose of this post is to start an open dialogue about how others would describe these decors, their similarities and their differences.
This is what I have observed. The photo from left to right is 1) Norma, 2) Delphi, 3) Silberiris. All with green grounds.
1) Norma appears to have the most dense application of gold and silver powder over the surface creating a thick, but still semi-opaque (almost pitted looking) covering. When you look at the glass from the inside, it appears as if there is a first layer of spots, and then multiple layers of gold and silver powder over it (or vice-a-versa). From the inside, the finish gives the glass a spotted look almost resembling the "Diana" decor. The finish also gives the glass a highly electric, multi-colored iridescence.
2) Delphi appears to have the lightest application of silver powder over the surface. It seems to be a layer of silver powder and then a second layer of silver-blue applied in spots. From the inside, the glass has a very faint blurred spot look. The finish gives it a faint silvery blue spotted finish that almost resembles Papillion.
3) Silberiris appears to be somewhere in the middle with a single layer of gold and silver powder. It is applied in an even fashion. From the inside there is no discernible spot pattern at all. The finish on the outside gives the glass a silvery gold almost metallic look.
Now, what do you think?
